ing railroad railsupon ties and particularly to rail chairs for this purpose.

r The general objectofjthe inven on s t0 provide a rail chair hav ng-means thereon which automatically engage the base flanges or the rails at the jcint between two rails and against lateralthrust or' tipping thrust, but

the iconstructionbeing" such as will'perniitg the relativelyfeasy detachment of the rails tromthe chair whenever necessary to replace the rails. 1

is; further object to provide a device of this character having ineans whereby the chair is, braced from the adjaeent rail'so y to hold the rails which rest npon the chair and the adjacent rail at proper'gauge or distance froine'ach other v Astill further object ifsto provide the l st named rail spacing means with means for. gripping the last "named rail which is released when the first named railsare lift-ed from the chair.

and upoii which thejrail rests, the'weight of the irailand the weight of the tiiain passing over-the rail acting to depressthe tail of the rail engaging members and causing the hook-like end .thereofto engage firmly overthe flange ot' the rail so thatlthe jrail cannot lift up while va train isupon the-rail and i cannot ordinarily .be lifted or detached from the chair except by manuallyIlift-ing .th' e rai l Verticallyupwardn V Other objects hare to do with the details of constructiort and tarrangement of parts as wil l appear mere fully hereinafterQ EMy invention is illustrated in the ac cQm 'panying drawings, whereinze F Figure-1. is top plan VlBW of a rail chair constructed in accordancefwith invention and showing it This invention relates to nieans for holdedge .of the ,rail'and Over the nia a the fish plate, if fish plates areusei.

Referring-to these drawings, 10 designates the body of a chair which 'is-inthe forrn of a plate and adapted to extend from oneitie A to a next adjacent-tie beneath the joint between two rails B. These rails B are shown as having the usual angular fish plates C. The base platelO or chair is preferably formed with-a pair or parallel, longitudinally extending, upwardly projecting ribs 11 which, are spaced apart so as to snugly receive the base of the rail between them and tend to prevent any lateral move ment of the rail. The lateral" margins of the line li -6 of plate are flanged at 12 and provided with screws 13*w-hereby the locks or latches may be held infirm engagement with the rails against accidental displacemen i The plate is forined with a plurality as, for instance, fourtransversely extending slots 1e. 1 have illustrated "four of theseslots but more slots may be used. -There are an even number ofthese slots 14 and the slots are disposed in staggered relation to each other. The under face'of the chair is provided on eachside of :the'se'slots with depending ears 15 and disposed in "each slot is a rail engagingimeniberor latch 16.' This has the form of a lever haying a depending car 17 which extends downward between the cars 15 and is pivoted therete by a transverse bolt 18.. @ne end ofeach latch is formed with an inwardly andupwardly e?- tending hoe] l9 and the latch is extended beyond its pivotal axis to form tail 20. The upper faces of these tails are upwardly beyeled, as will be seen from "Figure at Thus it will beobvvious that when a-rail is laid upon the chair 10 between the flanges 11, the base of the rail inayliiest upon these upper facesofthe locking levers 16 and en} gagingagainst the tails will farce the tails Qithe levers downward, causing thehooked e'ndsot the leversito be projected over the endof thetail is foriiied with a stop lug 21 which preve 'irts the tail of the fastenin'gudevice from being lifted too high and the -hook-shaped portion being depressed to too great anextent,

It will be seen that with this construction when a rail is laid upon the upper faces of the lever-like fastening devices they will depress the tails of these fastening dev ces, causing the hooks-to extend over the flanges of the rail. and thus lock each rail agalnst accidental upward movement. .Vhen the Weight of a train is upon the rails B, the

tails of the locking levers will be depressed with so'much force that it will be impossible for the railto leave the fish plate andthe rail will be locked securely thereon both against lateral movement, against tipping which pass through the flanges 12 ofthe chair and:engage against the ends of the thrust and against upward, movement. This is additionally prevented by the screws 13 latches, holding these latches raised. Obviously when the screwsiare removed the .latches may be depressed by first elevating the Iitiln" V v In order tospace the two rails of the track fromreach other and hold these rails properly spacedand at the proper gauge, I pro-' vide a spacing meanswhich compr ses a bar 22 which is forked at one end to embrace the baseplate or chair 10 and is bolted or riveted thereto, aS-at 23.

hooked, as at 24, to extend over the outer base flange. of the rail and the bar is slotted at 25, and disposed within this slot is a rail lock or fastener 26. This has a depending lug 27 through which passes a pin 28 which locke'xtends over the flange, as at 29, and 2 extends into the bar 22 to thus lock the fas-.

tener in-its rail clamping position. This the lock is pivoted at 26 to the bar 22, the lock extending downward through'the slot 25. Pivoted tothis extremity 30 is a longitudinally reciprocatable rod 31 held to the rod" 30v by a rivet, bolt or other suitable means. The other end of this rod is bifurcated and engaged with a bell crank lever 32 having trunnions 33. intermediate its ends.

' Theend of the lever 32 which is remote from the bar 22 extends downward and lat erally and the forked end of the rod 31 is pivoted tothis extension 34: by a rivet, bolt or other suitable means. The body of this lever 32 is disposed within a'slot 35 formed 7 in the bedpla-te or chair 10 preferably midway, of the widthof the chair'so that the whole weight of the rail rests upon the body portion of the lever, forcing it downward, thus exerting tension upon the rod ,31 which pulls upon the tail 30and causes the rail engaging extremity to be clamped down.

upon the base of the rail. Obviously when the rails on the chair are manually lifted This bar at its. end remote from the bifurcated port on isthis will relieve strain upon the lever 32 and then the rail engaged by the rail clamp 26 may be readily lifted by shifting the clamp 26 to its released position. This conbe understood that thechairs 10 will be used along the j oints'of both lines of'rail.

It will be seen that the construction which I have described. eliminates the. necessity for spiking the rails ,directlyfto the ties, with all the disadvantagesincident to these spikes as, for instance, the spike killing of the ties, rotting of the ties,-.etc. The ties will last a great deallonger forthe reason that the rails will rest at the joints upon the chairs .10, which in 'turn'rest upon two ties.

. The two rails at the joint willbe held much more firmlythan by the USByOf spikes and the rails will beheld in absolute alignment with each' otheryfllvhere spikes. are used, I

there is nomeans offholding the rails absolutely in alignmentfas the engaging, the end of one railmay shifter be pulled V out without afi'ectingthe other rail. NVith my construction, the adjacent ends ofiboth' rails'are firmly held inalignment and one rail cannot be removed without the ;other rail moving. '.;The construction elamps'the rail firmly to; the bed, particularly at. the time. when the wheels of a train are passing over the joint; [The greater thetipping thrust'on the'rail or strain upon the rail,

the greater theholding power offtherail clamping devices. Q
